为了筛选防治小麦赤霉病和控制毒素的高效杀菌剂，通过田间药效试验和小麦样品DON、ZEN毒素检测，研究了5种杀菌剂对小麦赤霉病的防病控毒效果。结果表明，200克/升氟唑菌酰羟胺SC + 250克/升丙环唑EC、40%丙硫？戊唑醇SC、48%氰烯菌唑？戊唑醇SC、50%戊唑？百菌清SC在小麦扬花初期和扬花盛期施用，对小麦赤霉病均有较好的防治效果，病指防效在85.16%~97.12%，对毒素也有一定的控制作用，控毒效果在60.03%~85.37%，未检出ZEN毒素。
In order to screen high-efficiency fungicides for the disease prevention and toxins control of wheat head blight, we studied the disease prevention and toxins control effects of five fungicides on wheat head blight, through field efficacy tests and detection of DON and ZEN toxins in wheat samples. The results showed that 200 g/L fluconazole hydroxylamine SC + 250 g/L propiconazole EC, 40% prothioconazole？tebuconazole SC, 48% cynoconazole？tebuconazole SC and 50% tebucona-zole？Chlorothalonil SC have a good control effect on wheat head blight, applied in the early and full blooming period of wheat. The control effect of disease refers to 85.16%~97.12%. They also have a certain control effect on toxins. The control effect is 60.03%~85.37%, ZEN toxin was not detected.
